I recently finished reading this book, entitled "Outliers", by author Malcolm Gladwell. This is an amazing book that outlines the lives and experiences of some of the most successful and accomplished human in history; including The Beatles, Bill Gates, and more. This video uses The Beatles as a reference, and explains the concept of "meaningful work." Let this inspire your playing.
